IMPROVEMENT IN BURGLAR-ALARMS.

Specification forming part of Letters Patent No. 213,936, dated April 1,1879; application filed February 1, 1879.

part of this specification.

My invention relates to a device for operating, adjusting, anddischarging fire arms charged with ball or blank in burglar-alarms; andthe novelty consists in the construction and arrangement of parts, aswill be more fully hereinafter set forth, and pointed out in the claims.

In carrying out my invention I employ a box of proper size and shape forthe required purpose, said box having a removable top, secured by screwsor otherwise. Rigidly secured to the bottom of this box is a frame orbridge, in a slot or mortise in which is pivoted a lever, from the outerend of which are cords leading in opposite directions, and passingthrough apertures in the side of the box. The opposite extremity of thislever is wedgeshaped, so as to afford but little bearing-surface on thetrigger-lever, against which it rests, and it is provided with avertical standard or marker, which extends through a slot in the coverand indicates the condition of the trap.

The trigger is pivoted in a slot or aperture in one side of the box, aportion thereof extending outside of the box, and adapted to operateupon the triggerof the fire-arm. It is provided with a slot, whichreceives the back end of the pivoted lever when iaa locked position, andhas a metal covered surface, against which the same rests when the trapis set. The inner end of this trigger is held with a constant forceagainst the pivoted lever by means of a spring, and a rod or rope isattached to the back side of the same near the end, and passes throughthe back-end of the box. The trap-surfacebf the trigger is situatedbetween the slot and end, and thesame may be set by the diflerent cordswithout opening the box.

A bearing-block for the arm, having a vertical slot, is secured to theside of the box, and by means of a set-screw may be adjusted verticallyat will. A similar block, forward, is adjustable vertically, and may bealso adjusted horizontally by means of a slot in that side of the box,so as to accommodate any length of arm. The arm rests in the upper jawsof these blocks, so that the trigger will rest within the finger-guardof the arm, forward of the trigger, as shown.

The operation of the invention is obvious, and the importance thereoflies chiefly in the simplicity of construction, efficiency, andcertainty in action, and in its non-liability to get out of order.

Figure 1 is a representation of a plan view, the cover being broken awayto show the in ternal mechanism; and Fig. 2 is a side eleva tion of analarm embodying the improvements in my invention.

Referring to the drawings, A represents the box, and A the cover.Secured to the bottom of the box A is a bridge, B, having aperture 1),in which is pivoted, at'b, a lever, 0, from the forward end of whichextend in opposite directions cords 0, which cords pass through the sideof the box at 0 The opposite end of this pivoted lever O is wedge-shapedat 0 and a marker,c ,extends upward and passes through a slot, a, in thecover A, as shown.

D represents the trigger, pivoted at d in the side of the box, andprovided with slot d, which receives the part 0 when in a lockedcondition. A metal covered surface, d affords but little friction whenthe trap is set, and a rope, E, &c., extends from the back through therear end of the box at e. A spring, F, holds the inner end of thetrigger with a constant force against the end of the lever.

Gr represents a set-block, having holdingjaws g for the pistol, &c., anda vertical slot, g, by means of which the same is vertically adjustable,a set-screw, a, holding it at any desired point. H represents a similarblock, having jaws h and vertical slot h but the bolt in this lattercase acts in a horizontal slot, I, in the side of the box, and the saidblock H is adjustable both horizontally and vertically, and may be heldat any desired point'by the set-screw no.

and slot 9, and the olock H, having jaws h and slot h, combined with thebox A, having slot I, the trigger D, its operating mechanism, and theset-screws, as specified.

In testimony that I claim the foregoing as my own I atfix my signaturein presenceof two witnesses.
